Objective: To review and assess the role of vitamin D on the onset, progression and relapse of multiple sclerosis (MS), based on evidence acquired from the analysis of preclinical, observational and interventional studies.

Methods: All English language literature in MEDLINE (January 1969-April 2012) was searched for observational and interventional studies on the dosage effect of vitamin D on the onset, progression and relapse rate of MS. The MESH terms used in the search included Vitamin D AND Multiple Sclerosis. Additional publications and abstracts were identified from review articles and from the references cited in the previously found articles. In addition to the experimental studies, only those human studies that specified the population size, doses of vitamin D used and the resulting effect on MS were considered.

Results: Vitamin D deficiency is very common among MS patients. Multiple preclinical studies have shown that vitamin D is a potent regulator of inflammation in MS. Most observational studies support an association between high vitamin D levels and a reduced risk of developing MS. However, conflicting results have been reported by observational studies on the correlation between vitamin D and MS severity and interventional studies using vitamin D as a therapeutic agent for MS.

Conclusion: Vitamin D deficiency in MS patients should be avoided. In addition, the risk of developing MS might be reduced by maintaining optimal vitamin D levels in the healthy population. Larger randomized interventional trials are needed to clarify the therapeutic effect of vitamin D in MS.
